The same image of the fallen leave was enlarged to fit on 9 tiles.
Since the original image is sharp and high resolution, the resulting
tile mural is also sharp and high resolution. The image quality
of the tile mural will decreases as the image size increases.
Here is some general rules for the image size and resolution in
dpi (dots per inch)
Superior resolution: 300+ dpi
Very Good Resolution: 200+ dpi
Good Resolution: 150+ dpi
Acceptable Resolution 100+ dpi
A 6Mpixel (3000 x 2000) digital camera can be enlarged to 30"
x 20" with acceptable images at 100dpi resolution.
For enven larger mural we have the computer technology that can
enlarge images to even larger size with a minimal loss of resolution
for wall size mural.
